Things I liked: Outstanding mount! Looks really nice and is super strong with super clamping force on the rail.

Things I would have changed: Nothing.

What others should know: Be sure you consider the height. For example this medium is ideal for most things imo, and I much prefer the lower stance over a high mount. So far I have not needed a high for any gun, but I limit my scopes to 40AO and 44.
Example; I have a generic 3-9x40AO Centerpoint (bundled with Crosman/Benjamin guns) that I just measured and the largest part of the obj housing is 2.1", and the cap brings it to ~2.3. Mounted on a generic Crosman break barrel (Titan), with no shims, the dust cap is tight on the receiver so it needs maybe .010" sanded off at that spot. Without the cap there's .060" clearance which is plenty for (most) shimming needs. The cap can be sanded all the way thru if needed so the same clearance would apply. Fyi; scopes, guns and mounts can vary with mfg changes over time etc., but at least you have some info to go on.
If by chance you need extra super clamping force then consider the one-piece version PY-A-805 because you can drill/tap to add two more screws.
